SPECIFICATION forming part of Letters Patent No. 433,018, dated July 29, 1890.

Application filed April 16, 1890- Serial No. 348,230. (No model.)

T aZZ whom it may concern.-

Be it known that I, FLOYD ELRAGE MONT- GOMERY, a citizen of the United States, residing at Clarinda, in the county of Page and State of Iowa, have invented. a new and useful Cultivator, of which the following is a specification.

This invention relates to cultivator-s; and it has for its object to construct a machine of IO this class which shall possess superior advantages in point of simplicity, durability, and general efficiency.

\Vith these ends in view the invention consists in the improved construction and ar- 5 rangements of the detailed parts of the machine, which will be hereinafter fully described, and particularly pointed out in the claims.

Like numerals of reference indicate like parts in all the figures.

A complete cultivator embodying my improvemeiiits is provided with two separate standards or, as I term them, movements,

which in the drawings hereto annexed have been. designated by 1 1. These movements are constructed precisely alike, and each is composed of two separate parts or sections 2 2, one of which has been shown in detail in Fig. 6 of the drawings. The said parts 2 are each composed of the flat plate 3, provided at its lower end with an outwardly-diverging shoulder 4, from which a plate 5 extends in a downward direction. The plates 5 are provided with rearwardly-extending brackets 6, having means for the attachment of the cultivator-beams, as will be hereinafter more fully described. The portions 3 and 5 of the devices are provided on their outer sides with vertical strengthening-ribs 7. The plates 3, the inner sides of which are normally in contact with each other, are provided at their upper and near their lower ends with the semicylindrical flanges 8, the outer edges of which are provided with slots or notches 9.

Theparts 2 2 of the movements or standards are connected by the coupling-caps, which are designated,respectively, by 10 and 11, and which engage the flanges S at the upper and lower ends of the plates 3. The said couplingcaps are provided with forward and rearward extending arms 12, which are connected by means of bolts 13, thereby serving to connect the parts 2 2 firmly'and yet in such a manner as to permit the movement orstandards to oscillate within the said coupling-caps, which latter are provided with flanges 14 to engage the flanges S, as will be seen most clearly in Fig. 4 of the drawings.

The flanges ll of the coupling-caps l0 and 11 are provided with inwardly-extendinglugs 15 to engage the notches or slots 9, and thereby to limit the oscillating movement of the devices.

The downwardly-extending plates or parts 5 of the movement or standards are connected by means of a bolt 16, upon which a sleeve 17 is interposed between the said plates 5 to keep them the desired distance apart. A lug or key 18 serves to prevent the sleeve 17 from rotating upon the bolt. This sleeve is in the nature of a strain-block, and it must be made sutficiently strong and rigid to resist the pressure which is caused by the mounting of I00 the spindle upon the bolt 16, as will be presently described.

The'spindles, which are two in number, one I for each movement, are designated by 19,and are of ordinary construction, being provided at their inner ends with collars or flanges 20 and at their outer ends with cap-nuts 21. Each of the spindles is provided at its inner end with an upwardly extending arm or bracket 22, provided on its inner side with flanges 23 to engage the ribs 7 upon the outer side of the adjacent plate. The outer side of the arm or bracket 22 is provided with transverse teeth or corrugations 24, adapted to engage corresponding teeth or corrugations 25 in a block 26. The bolt 16 extends through a vertical slot 27 in the arm or bracket 22 of the spindle and through a perforation in the adjusting-block, when by tightening the nut upon the said bolt 16 the parts will be secured together very firmly and rigidly and at any desired adjustment, which will be regulated by placing the spindle at any desired height. The block 25, it will be seen, is not capable of vertical adjustment, but only serves to retain the spindle at any adjustment at which it may be placed. Said block is provided at its front edge with a vertical flange 28, the purpose of which will be hereinafter described.

The arms or brackets 12 of the couplingcaps 10 and 11 of each movement are provided in their meeting faces with notches or recesses, which, when the parts are placed together, form the slots 29. Said slots are for the reception of the ends of the arched or curved guards 30, which form, practically, the arched axle of the cultivator. The ends of the said arched bars are provided with V- shaped notches 31, to be engaged by V- shaped lugs 32, formed in the inner sides or ends of the slots 29, therebyserving to retain the arched axle-bars securely in position without possibility of displacement and without tightening any of the connecting-bolts to such an extent as to injure any of the parts connect-ed thereby.

Between the rearward-extending arms or brackets 12 of the lower coupling-cap 11 of each movement is interposed an upward and rearward extending arm or bracket 33, which is held securely upon the connectingbolt 13, and which serves in practice for the suspension of the cultivator-beams when the latter are to be thrown temporarily out of operation, as will be seen in dotted lines in Fig. 1 'of the drawings.

34 designates the draft-hooks, which are provided with rearward-extending arms designated, respectively, by 35 and 36, the former of which are provided at their rear ends with perforations 37, whereby they are mounted upon the sleeves 17 on the bolts 16. The rear ends of the arms 36 are provided with hooks 38, which are hooked into slots 39, formed in the plates 5 near the lower ends of the latter. It will be seen that by means of these drafthooks the draft may be attached independently, as it were; to each movement. At the same time the draft will in operation be perfectly equalized by mechanism forming part of' my invention, and to be hereinafter more fully described.

40 40 designate arms or bars which are mounted upon the outer ends of the bolts 16, adjacent to the adjusting-blocks 26 and resting or hearing against the flanges 28 at the front edges of the latter. Said arms 40 are provided at their outer ends with hooks 41, extending from the upper edges, and near their outer ends they are provided with transverse bolts 42.

43 designates extension-bars or drive-bars, which are provided with slots 44, by means of which they are mounted plvotally upon the bolts 42. The slots 44 admit of the longitudinal adjustment of the drive-bar 43, and the latter, when desired, may be folded upon the arms or brackets 40. These drive-bars serve in operation to some extent to support the axle and to aid the machine in passing obstructions. The spindles are to be provided with supporting-wheels 45 of ordinary construction.

The rearward-extending brackets 6 of the movement-standards are provided with ann ular bosses or flanges 46, surrounding perforations 47 therein. Said perforations 47 are provided near their front ends with lugs 48,

and the brackets 6 are provided on their rear sides with eccentric lugs or teeth 49.

5O designates the cultivatorbeams, which are provided at their front ends with vertical slots 51, in which are seated the couplingplates 52, the upper and lower edges of which are provided with flanges 53 to bear against the upper and lower sides of the beams, and which are secured in position by means of the transverse bolts 54. The front ends of the coupling-plates 52 have forward-extending arms 55, which are connected by the vertical pins or bolts 56 to form clevises. These clevises are connected with the draft-brackets 6 by means of the beam-coupling plates, one of which has been shown in detail in Fig. 8 of the drawings, and each of which is provided with a laterally-extending boss 56 to engage the flanges 46 of the draft-brackets. The bosses 56 of the plates, which latter are designated by 57, are provided with notches 58 to engage the lugs 48, formed in the perforations47 of the draft-brackets. The coupling-plates 57 are provided with transverse ICC) perforations 59 and 60, the former of which grooves 62, adapted to receive the vertical pins or bolts 56 of the clevises at the front ends of the cultivator-beams. It will thus be seen that by tightening the coupling-bolts 60 and 63 the parts may be firmly connected in such a manner as to permit the cultivator beams to swing or oscillate both laterally and vertically, thus connecting the said cultivato rbeams with their respective movements by practically universal joints. At the same time it will be observed that the movement in a downward direction of the cultivatorbeams will be limited by the lugs 56 engaging the bolts 61 and by the notched bosses 56 engaging the lugs i8, as hereinbefore described. The cultivatonbeams are provided in the usual manner with standards 64, carrying shovels 65 of ordinary construction. Said beams are also provided with handles 67, by means of which they may be guided during operation.

\Vhen listed corn is to be cultivated, I avail myself of the fenders which have been shown in detail in Fig. 11 of the drawings. Said fenders, which are to be attached to the standards 64, consist of the inclined bearing-plates 68, having rearward extending horizontal brackets 69 and 70, between which is pivoted a wing or plate 71. The latter is provided with a transverse bolt 72, upon which the fender-plate 73 is pivotally mounted. Said fender-plate, which is preferably constructed of sheet metal, is provided near its front end with a segmental slot 74, concentric with the bolt 72. Through said slot extends a transverse bolt 7 5, which also extends through the wing or plate 71. Upon the said bolt 75 is pivotally mounted a hand-lever 7 6, the front end of which is adapted to engage any one of a series of notches or recesses 77, formed in the under side of the arm or bracket 60. By this mechanism it will be seen that the fenderplate may be adjusted laterally to any desired angle with relation to the standard to which it may be secured. Vertical adjustmont of the fender-plate may be had by loosening the nut upon the bolt 72, thus permitting the said plate to be tipped or tilted within the limits of the length of the slot 74. 7 8 designates the cultivator-tongue, which is secured by means of a vertical bolt 79 between the flanges 80, formed at the sides or ridges of a circular seat. plate or disk 81. The latter is provided with downwardly-extending studs 82, working in segmental slots 83, formed in a circular disk or tongue-table 84, which latter is provided with downwardlyextending lugs, which are bolted or otherwise secured to the front and rear arched axlebars 30. It will be seen that by this construction the tongue is connected pivotally with the axle-bars in such a manner as to be capable of swinging in a horizontal plane to an extent limited by the length of the slots 83. At the same time the connection of the tongue with the arched axle-bars is very firm and durable, and the said axle-bars are materially raised and strengthened by the said connection.

The cultivator-bea1ns are provided with hooks 86, by means of which they may be temporarily suspended from the arms or brackets 33, as will be seen in Fig. 1 of the drawings.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of my invention will be readily understood by those skilled in the art to which it appertains. My improved cultivator combines the advantages of the tongue or tongueless sulky. It secures an independent hitch or attachment of the draft without losing perfect control of the gangs. It provides for the attachment of the hitch to the point of the beam without the medium of doubletree. The gangs in opera-- tion move not only independently of each other, but move backwardand forward in line of progression and always at the same distance apart. There is no side draft, and consequently no drifting of the gangs sidewise. The machine may be turned in the shortest possible space, and cannot possibly fall down or become tangled in the operation. The draft is perfectly equalized, and the gangs or beams are so constructed and arranged that they may be managed or manipulated very easily and conveniently.

The general construction,arrangement, and combination of the parts of the invention are simple, durable, and inexpensive, and the machine embodying my improvements may be produced at a smaller expense and operatcd with better results than most machines use.
